Screen got stepped on a while ago, worked but was cracked. Got one on eBay, installed it, and it worked okay for about 10 minutes, then when my back was turned, made a nice few second beep noise, and shut off.
Battery hasn’t worked in this thing for a while. I get a green light on the magnetic power adapter plug, and yellow/green flashing when the useless battery is installed.
Tried to reset the SMC to no avail. Did I cook the motherboard? Haha
